Book translates it as 'Lorca's Charm' (1,9,5)
I believe the answer is:
a christmas carol
'book' is the definition.
(I've seen this before)
'translates it as lorca's charm' is the wordplay.
'translates' indicates anagramming the letters (I've seen 'translated' mean this).
'it'+'as'+'lorcas'+'charm'='itaslorcascharm'
'itaslorcascharm' is an anagram of 'A CHRISTMAS CAROL'.
(Other definitions for a christmas carol that I've seen before include "Seasonal song" , "haunting story for 8 [EBENEZER SCROOGE]" , "Scrooge's tale" , "Classic book" , "novel" .)
